Claude Code Was Burning Tokens Until I Put a Gate in Front of It

A Claude Code hook blocks unbounded searches and full-file reads, then suggests safer commands to reduce context bloat and token usage.

Did you ever regret doing a project in Rust?

I think weve all seen the Fireship video discussing the Bun rewrite in Rust. "Just do it in Rust" is being championed on the web as a general no-brainer like "move more and eat more vegetables." Playing the devils advocate, did you ever regret going with Rust on a given project? submitted by /u/BigBootyBear [link] [comments]

Left of the Loop: The Phoenix

Herodotus wrote of a bird that lived five hundred years in Arabia, and when its life came to an end, it did not wait to be surprised by death. It built its own nest of cinnamon and myrrh, set the nest and itself alight, and let a new bird rise from what the fire left behind. The Hestia argued for tending a fire that must never go out. That’s true, and it isn’t the whole truth. Teams end. People...

The First 90 Days of Learning IT

A realistic 12-week structure that turns enthusiasm into visible proof. The problem You are motivated now, but motivation fades, and without a structure the first three months of learning IT dissolve into random videos. A realistic 12-week shape keeps you moving and produces proof along the way. Why this matters now With more people self-teaching IT, the people who succeed ...

I rebuilt a viral "3,888% return" TradingView strategy — it landed almost exactly at coin-flip odds

A trading YouTube channel (Trading with DaviddTech) posted a video claiming a "strange 63% win rate" TradingView indicator, turned into a full strategy (three indicators stacked together, nicknamed "Manergy Cloud" in the video), backtested on BTCUSDT at 1-hour bars with a claimed 3,888% total return, 62.8% win rate, profit factor 2.1, over 237 trades — using 10x leverage. I wanted to actually tes...

How Much of Your CI Pipeline Is Just Cucumber Scenarios You're Too Afraid to Delete

The CI job just hit 28 minutes. Again. You pull up the duration report expecting to blame a bloated integration test or a slow environment spin‑up. Instead the longest stage stares back at you: a collection of Cucumber feature files that haven’t caught a real bug in months. Maybe years. They run on every commit, green circle after green circle, while your team mutters about slow pipelines and nob...

3 Portfolio Mistakes Hiring Managers Spot Instantly

The manager opens your portfolio. Your resume says you have five years of automation experience. The README lists Selenium, Playwright, Appium, Jenkins, Docker, Kubernetes. He scrolls. There is no code. The browser tab closes. This is you. Not because you lack skill—you have it—but because your public proof reads like a shopping list. The tools you name say nothing about how you think when a fla...

The Manual Tester Who Can Write a SQL Join Will Always Beat the SDET Who Can't

Most people think the SDET title means you are automatically more valuable than a manual tester. The SDET writes Playwright scripts. The SDET configures CI pipelines. The SDET talks about page objects and retry strategies. The manual tester clicks through screens and writes bug reports. Here is the truth I have watched play out across teams: the manual tester who can write a SQL join will consis...

SigNoz Hackathon

I built an AI agent system that automatically switches to a backup AI model if the main one fails. I connected every step to SigNoz so I could track requests, monitor performance, and detect failures. I also built a diagnostic agent that reads the monitoring data and explains the reason for failures in simple language. During testing, it successfully detected a real AI provider outage and identifi...

How to Audit an Anchor Program: A Practical Checklist

Auditing a Solana program isn't about reading every line top to bottom and hoping something jumps out. It's about knowing the small set of places where Anchor programs actually go wrong and checking each one deliberately. This guide walks through that process in the order an experienced reviewer would follow, and ends with a checklist you can paste into your review notes. Anchor does a lot of val...

I was tired of coding alone in cafes, so I built a "radar" to find other developers nearby.

If you are a remote developer or an indie hacker, you probably know the feeling: You take your laptop, go to a local coffee shop or a coworking space to escape the isolation of your home office. You sit there for 4 hours, typing away. You look around and see three other people with MacBooks, VS Code open, clearly working on something cool. But you never say hi. Why? Because interrupting someone ...

Run Kubernetes in Docker on Ubuntu for Local Development

There's a delightfully literal answer to "Kubernetes with Docker": kind — Kubernetes IN Docker. Each node is a Docker container running a full Kubernetes node image. On an Ubuntu workstation it gives you a real, throwaway, multi-node cluster in about 30 seconds. It's my default for local dev and for CI. Prerequisites on Ubuntu You need Docker Engine and kubectl. If you don't have Docke...
